| Abstract: | Codonopsis lanceolata Benth.et Hook was taken as the material in this study,after the observation of its flowering habit ,we found that the stamen has the characteristic of pollen dispersing.The results of the trials of hybridization and self-pollination indicated that the optimum features of the castration of buds were buds with olivine,but without change color of its top,five stamens were distributed around closely to the stigma after peeling the buds and mature anther without crack and Pollination.The height and diameter of the buds were 1.9-2.3 cm and 1.6-2.1 cm,respectively.Features of mature anther and the optimum time of pollination were anthers with three carpals outspreading like a sector and the fringes of them were wrapped and reversed after manual castration 5 or 6 days. |
